Rom 10:18

10:18 Their voice has gone out to all the earth. The immediate context of the citation from Ps. 19:4 is that of God’s general revelation (Ps. 19:1–3). Paul’s use of it to prove from Scripture that Israel has heard the message of God implies that his quotation of this section of the psalm carries with it the teaching of the entire psalm, which speaks of both general revelation in nature and special revelation in His word. The latter takes place in the context of the former. The underlying logic may be: If those without special revelation have “heard” the message of God’s glory in creation, how much more have those who received special revelation heard that message.
